Hello and welcome to HCM forum,
According to the dental history provided by you i would like to inform you that when a tooth is associated with an abscess
, antibiotics have to be prescribed in order to treat infection.
It is pus which is discharging and is responsible for foul odour , once the infection resolves, pus will disappear .
is also one of the symptoms associated with infection, currently your medication does not include antibiotics, therefore kindly see your dentist
Perform warm saline rinses(3-4times/day), it will help relief symptoms.
use an antibacterial mouth rinse(twice/day).
i hope i answered your query,
i wish you good health.
